I had one a while ago and while it was cool to take apart and put back together, I prefer the folding stock on my 10-22:
1. not much longer overall than the TD
2. can fire it with or without the stock folded
3. don't have to fumble with separate parts in the dark, in a vehicle, on the run, etc.
4. once SHTF you'll probably be open-carrying, in which case the folding stock is much more portable
5. I don't like fiddling with the barrel tensioning do-hickey (is it as tight as the last time?, did I overtighten it? etc)
so I ended up selling my TD.
The coolest thing was the bag it came in, so I've ordered another one. Not really a stealthy bag, what with that big red turkey (or whatever) embroidered on it, but when you take it to the range everyone knows what's in it.
Don't get me wrong--I like the TD and I think it's cool (and I'm buying another one), but I prefer the folding stock version.
